Evolution of a Revolution

Q:

I have a need to rehabilitate some aging URD circuits. How long have Novinium fluids and injection technologies been in use? I prefer to use proven technology.

A:

Are you still using an Intel® 8086 processor? The processor was introduced in mid-1978. If you are still using an 8086 you’ll probably want to use continuous air drying or perpetual injection of acetophenone to extend the life of your cable. On the other hand, if you have a modern microprocessor in your computer, you’ll probably want the suped-up version of those older rejuvenation technologies, which were introduced in the early 1980’s.

I suspect that what you really want to consider is not the number of years a specific fluid has been used, but the evolution and lineage of the products and processes available to you. Just like Intel upgrades the capabilities of its processors every 18 to 24 months, the two global rejuvenation vendors do the same thing—each at a different pace. There are no commercially significant rejuvenation fluids used today, which have been in use without formulation changes for more than six years—that’s a fact. The more relevant answer to your question requires a discussion of the “evolution of a revolution” in small diameter (cable conductors 4/0 and smaller) cable rehabilitation. Check out the chart nearby, which is a kind of rejuvenation genealogy.

There are two main dimensions to rejuvenation technology, fluid and process. The evolutions of both of these dimensions are presented alongside the innovation timeline down the middle of the illustration. The innovation timeline provides inventor names, patent application dates, and the U.S. Patent number of all commercially significant innovations in the rejuvenation of small diameter cables. The timeline stretches 30 years from 1981 to 2011. The very first inventors, Fryszczyn and Bahder were both with Cable Technology Laboratories (CTL). They invented two methods of perpetual continuous feed, one that involved a flow of desiccant (typically dry air or nitrogen) and the other involved non-water reactive (NWR) hydrocarbons such as fatty-alcohols and acetophenone. Neither of these two ideas enjoyed substantial commercial success, because the notion of perpetually maintaining flow in a cable was not attractive. The air-drying approach survives today in some small volume specialty applications.

After the groundbreaking work at CTL, all innovation since 1986 was led by Novinium founders, Bertini and Vincent. That’s right, every significant improvement in the fluids and the process involved these two men. In 2005, the formulation of Cablecure® XL product was changed by reducing the level of the very volatile and flammable monoalkoxysilane (MAS) additive by a factor of six, hence the Cablecure XL fluid in use today has been in use for about six years. This happens to be about the same length of time as Novinium’s fluid offerings, but what is really important is the lineage.

As you can see from the illustration, there is an unbroken lineage of fluid and process improvements that trace back over three decades. The majority components of all rejuvenation fluids since 1986 have been water reactive dialkoxysilanes (DAS). Patented improvements made by Novinium and represented in the figure with a light blue background include:

iDAS—improved-dialkoxysilanes provide longer life.

iNWR—improved-non-water-reactive components do not suffer the fire hazard of the MAS component in CableCURE/XL, but provide a variety of short and long-term performance benefits.

Improved catalyst—all but eliminates the need for uneconomical and dangerous soak periods.

SPR—Sustained Pressure rejuvenation, together with the chemistry changes above, doubles life-extension.

iUPR—Improved Unsustained Pressure Rejuvenation eliminates the soak period, saving time and improving safety.

More historical perspective is available in a paper titled, “History and Status of Silicone Injection Technology” presented on October 4, 2007 at the Energy Council of the Northeast’s (ECNE) Engineering and Operations Conference. Click here to see that paper.

If you are still using Intel’s 8086 microprocessor, you do not want to do business with Novinium, because we are never satisfied. We will continue to make incremental and, occasionally, revolutionary improvements in our fluids and our processes. Only at Novinium can you interact with the development team that made rejuvenation possible. For your project the lowest risk is achieved by selecting the world’s leading experts.

I for one embrace the state-of-the art and the reduction of risk by the judicious application of technology.
